CARCOUPLING.

SPECIFICATION forming part of Letters Patent No. 554,970, dated February18, 1896.

Application filed November 30,1895. Serial No. 570,718. (No model.)

To all whom, it may concern:

Be it known that I, OYEUs F. BAKE, a citizen of the United States ofAmerica, residing at Fullerton, in the county of Nance and State ofNebraska, have invented certain new and useful Improvements inOar-Couplings; and I do hereby declare the following to be a full,clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The object of this invention is to provide an improved car-coupling andmeans for holding the locking-bar out of an operative position; and itconsists in the construction and combination of the parts, as will behereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figurel is a vertical sectional view of a car-coupling constructed inaccordance with my invention. Fig. 2 is a plan view of the draw-bar andcouplinghead and parts to which they are connected, the coupling-headbeing partly in section. Fig. 3 is a detail perspective view of themeans for holding the locking-bar out of an operative position. Fig. 4tis a plan view of Fig. 3, and Fig. 5 is a plan View of thecoupling-link.

A designates the coupling-head and B the draw-bar which passes through acentral longitudinal aperture in the coupling-head and is attachedthereto by a transverse pin b, the forward end of the draw-bar beingformed into a head, which lies in a corresponding recess in thecoupling-head. The couplinghead A is preferably made of a casting shapedso that the sides converge rearward, as shown in Fig. 2. The draw-barand coupling-head are attached to the car by means of longitudinal beamsO and C', which are secured to the under side of the car, to besubstantially parallel with the sides of the couplinghead and a slightdistance therefrom. The beams are connected to each other by crosspiecesc c, c', and c2, the cross-pieces c c lying in recesses in the upper andlower sides of the coupling-head, while the cross-piece c' has anaperture through which the rear end of the draw-bar passes, and theforward end of the coupling-head rests upon the cross-piece c2.Encircling the draw-bar and interposed between the cross-piece c and therear end of the coupling-head A is a helical spring C2, the tendency ofwhich is to force the coupling-head forward, the movement in bothdirections being limited by the length of the recesses c c hereinbeforereferred to. It will also be noted that an excessive rearward movementof the coupling-head would be prevented byits jamming between the beamsO and Ct, the arrangement of said beams providing for this.

The link-chamber of the coupling-head tapers rearward, as shown in Fig.2, and in the upper wall of the same is formed a recess in which thelocking-bar D is pivoted, the forward end of the recess forming ashoulder a", against which the shoulder a2 at the forward end of thelocking-bar bears when its free end is engaged by the coupling-link. Tothe free end of the locking-bar is connected a link d, which extendsthrough an aperture a3 in the upper part of the coupling-head and isconnected to the device hereinafter described for raising thelocking-bar and holding it in a raised position. The forward end of thecoupling-head is provided with vertical apertures to receive theordinary coupling-pin.

E designates a casing or housing, which is provided at its lower endwith outwardly-projecting flanges e, by means of which it is secured tothe top of the car, and within this casing or housing is pivoted a blockF, said block being preferably of metal, to give it weight, and is inthe form of a segment, as shown in Fig. l,the pivot-pin f passingthrough the same adjacent to the angle thereon. To the forward end ofthe segment or block F is attached a chain or flexible connection f saidchain being also attached to avertical rod d', which is connected at itslower end to the link d, extending from the locking-bar D. rIhe rod d'is guided in suitable links or eyes attached to the forward end of thecar, and the lower end of the same is bent outward, as shown, to engagethe link d.

The rear end of the upper part of the casing or housing E is cut away,as shown in Fig. 4, to provide for the movement of alever IOO 1o f2 inthe segment or block.

F, which is secured to the rear end of the segment er block F andprovides a means for operating the same to raise the locking-bar l). Tohold the locking-bar in a raised position or out of operation the casingE is provided with a gravity-catch Gr, which is pivoted betweenapertured ears e e thereon and has a projection g, which passes throughan aperture in the casing and engages an aperture The outer end of thecatch is weighted to cause the projection g to automatically engage theaperture in the segment or bleek, and in order to operate said catchfrom the side of the car I attach a ilexible connection or cord gthereto and lead said cord to a suitable point at one side of the car.

The device herein shown and described is an improvement upon my previouspatent, No. 160,294, dated March 2, 1875.

The operation of the parts will be readily understood from the drawingsand foregoing description, the coupling of the cars being automatic whenthe lockingbar I) is lowered, as shown in Fig. l, for in this positionthe link lI, when it passes into the coupling-head, will raise thelocking-bar, and the latter passing over the head 7L of the link willfall into position to engage the shoulder 7L thereof, the jar occasionedbythe coupling-heads coming together being taken up bythe helical springC2, and when the train is being drawn forward the pivot-pin of thelocking-bar will be relieved. of strain by the shoulder d on the upperpart of the link-chamber. When it is desired that the ears should notcouple when they come together the locking-bar D may be held out of auoperative position by swinging the segment or block F back until theaperture f2 therein is engaged by the gravitycatch G.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Iatent, is-

l. The combination in a car-coupling, of a coupling-head shaped topresent side walls which converge rearward, a draw-bar passed through acentral longitudinal aperture in the couplingwhead and having a headwhich lies in a corresponding recess in said coupling-head, the draw-barbeing secured to the coupling* head by a transverse pin; together withlongitudinal bars or beams C and C converging rearward and havingcross-pieces c c, c', and c2 rigidly secured thereto with which thedrawbar and coupling-head engage, and a helical spring encircling thedraw-bar and interposed between the cross-piece c and the couplinghead,the coupling-head being recessed to receive the cross-pieces c c,substantially as shown and for the purpose set forth.

2. In a ear-coupling, the combination with the coupling-head having ashouldered locking-bar pivoted therein, of a segment or block F pivotedwithin a casing and having an aperture or notch in one side of thesaine, and a gravity-catch pivoted on one side of the casing and havinga projection which engages the aperture or notch in the segment, thesegment being connected to the locking-bar, sub stantially as shown andfor the purpose set forth.

3. In a car-coupling, the combination with the coupling-head having alocking-bar piv oted therein, of a casing or housing E secured on top ofthe car, a segment F pivoted in said casing or housing and provided atits rear end with an operating-lever FQ a gravity-latch G pivotcd on oneside of the casing and provided with a projection g adapted to engage anotch or aperture in the segment, and a cord extending from thegravity-latch to a point at one side of the car, the segment beingconnected to the locking-bar by a flexible connection f, rod d' and linkd, substantially as shown and for the purpose set forth.

In testimony whereof I aiiX my signature in presence of two witnesses.
